In pictures: A look inside abandoned Heyford US Air Force base in Oxfordshire

Once allegedly used for storing nuclear warheads in case of an attack on Moscow, RAF Upper Heyford in Oxfordshire now stands abandoned and decaying. Used by the Royal Air Force primarily as a training base from 1918 to 1950, the site was transferred to the United States Air Force (USAF) at the beginning of the Cold War.Picture: Darmon Ritcher / Barcroft Media
